A huge, ocean covered exomoon?

Possible exomoon may be an ocean-covered world as big as Saturn

In July, tantalising evidence emerged of the first discovery of a moon around a planet beyond our solar system. Although the exomoon’s existence has yet to be confirmed, new results show that the world may look stranger than anyone thought and may also have been created through some unknown mechanism.

David Kipping at Columbia University, New York, has spearheaded an effort to comb through Kepler spacecraft data in search of hidden moons since 2012. Back in July, he and his graduate student Alex Teachey announced they had found signs of a colossal exomoon that might orbit a gas giant roughly 4000 light years away.

I think there is probably more Earth size habitable moons than planets.

Based on what?

The going theory is Jupiter migrated in and cleared the larger rocky planets giving a chance for the current smaller ones to form. That doesn't seem to  be the rule. Many exoplanets are "super" gas giants. Why wouldn't they capture smaller rocky planets in their migrations or during their formations? I'm talking about "sun like" stars though. I think there would be too much solar activity and radiation for anything to be habitable for us around a red dwarf.
